I'm cooking up a concept that involves launching something into the air. I know that this can be allowed, but I'm pretty sure that just doing it without letting anyone know you're going to do it would cause some major wrath.
So, yous of you who actually have some experience and knowledge in this area, what's the deal?
I do want to mention right off the bat that I'm looking to use air pressure and a parachute to avoid moop.
Thank you in advance for your kind sharing of knowledge.

When I got back to my camp late on burn night I found, right in front of my tent a big aluminum rocket casing. This thing is big, and the fins on it are hella sharp. It deff would've done some damage if it would've hit somebody when it came down. I'll post pix later tonight after I get home. I've read the back of the ticket, and yes I'm aware of the dangers out there, and no, it didn't hit anybody, but still, for a rocket to come down way back on 4:30 and Hanoi...
